hello Remy,
	thanks for your support.
	the error i got is this

arm-linux-ld:
ERROR: /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_udivdi3.oS) uses hardware FP, whereas u-boot uses software FP
arm-linux-ld: failed to merge target specific data of
file /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_udivdi3.oS)
arm-linux-ld:
ERROR: /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_clz.oS) uses hardware FP, whereas u-boot uses software FP
arm-linux-ld: failed to merge target specific data of
file /usr/local/arm/4.1/bin-ccache/../lib/gcc/arm-linux-uclibc/3.4.6/libgcc.a(_clz.oS)

and i solved this by commenting the "-msoft-float " option for compiler
in cpu/arm926ejs/config.mk & cpu/arm926ejs/at91sam926x/config.mk

but what makes me think is that same flag was given for at91rm9200
and it worked.

thanks & regards
